I remember when DVD first came about, one of the selling points was going to be Pan 'n Scan on the fly. Essentially, the disc authorers would encode an anamorphic copy of the film. Then, they would apply instructions for the DVD player to scan on the fly. The end result would be both P&S and Widescreen on the same disc, but without the bit rate sacrifice required for two complete versions of the film. Why didn't Disney do that for Monsters, Inc. if this still exists in the DVD spec?

To the best of my knowledge it's still in the spec but no DVDs, or at any rate hardly any DVDs, have ever used it.

The issue may be that the commonly-used DVD authoring software doesn't provide good support for creating dynamic pan/scan titles, or that it's extra work that the studios don't want to bother with. They have to create a hard-formatted pan-and-scan version for the television market anyway, so it's no big deal to simply slap it onto the disc.

It just seems that the negative reviews of Monsters, Inc. all mention that picture quality would have been better, had they not included both versions on the same disc. Whatsmore, the extra room would have afforded a DTS track. Pan & Scan on the fly would have avoided these problems, no?

Monster, Inc was reformatted digitally for 1.33, not pan & scanned. DVD's pan & scan on the fly will not work with aspect ratios higher than 1.85 (like 2.35 films). It is also one of those untested features that may not work properly in all DVD players.

Pan and Scan on the fly has been used for a large number of DVDs, just not in the method that many think. Anamorphic menus are all done with pan and scan on the fly. If your TV is set as 4x3 or 4x3 letterbox, it will zoom in on the menu screen, effectively chopping it off.

Paramount also does it with their copyright screens.

Pan and scan on the fly isn't done most likely because it actually is WORSE than pan and scan in terms of framing and because a VHS transfer needs to be done anyway.

Personally, I say that if people want to remain ignorant or pig-headed about it, they deserve to watch an even poorer framed film, but whatever.
